Webinar 20: Emerging Issues in Forensic Genealogy

Emerging Issues in Forensic Genealogy
November 17, 2020
1:00 p.m. - 3:00 p.m. EDT

In Emerging Issues in Forensic Genealogy, Investigative Genetic Genealogy (IGG) Consultant, Barbara Rae-Venter discussed the Golden State Killer (GSK) case and the methodology used to identify DeAngelo as a suspect. Also included, with permission, are some slides from Stephen Kramer of the Los Angeles field office of the FBI whom Barbara worked with on the GSK case. This case illustrates not only the power of IGG but the enormous cost savings and minimal intrusiveness, amongst other benefits, of IGG vs traditional law enforcement (LE) research.

In the second half of this webinar, Tiffany Roy, Forensic DNA Expert, covered emerging trends in forensic genetic genealogy (FGG). The presentation bridged the gap between science and law by explaining the differences in the scientific testing used for databases like GEDmatch, compared to traditional STR testing used by government labs today. The differences in information obtained through this new testing are discussed along with the legal issues presented by these differences. Finally, the Department of Justice interim guidelines on FGG were reviewed, along with database user agreements and potential legal issues that can arise in an investigation employing FGG.

Barbara Rae-Venter, J.D., Ph.D., is a retired intellectual property attorney who specialized in the patenting of biotechnology inventions. She earned a J.D. from the University of Texas at Austin Law School, a B.A. double major in Psychology and Biochemistry, and a Ph.D. in Biology from the University of California at San Diego.

Through the use of investigative genetic genealogy (IGG) techniques, Ms. Venter has been able to identify the abductor of Lisa Jenson, three victims of the Allenstown Four murders, and the Golden State Killer. IGG is now being used to solve many previously “unsolvable” cold cases.

Ms. Venter was recognized for her work by the journal Nature as one of “10 People Who Mattered in Science in 2018” and was named among the Time 100: Most Influential People of 2019.
